Abstract
A modified aluminosilicate in powder form comprising alkali metal silicate deposited onto aluninosilicate of the zeolite P type particles presents increased liquid carrying capacity.
Description
Invention field
The present invention relates to a kind of modified aluminosilicate, more ad hoc relate to a kind of modified aluminosilicate in detergent composition P type zeolite commonly used.
Background of invention
Use P type zeolite in the detergent formulation, for example in European patent Shen 0384070 (Unilever company), be identified.
P type zeolite comprises a series of synthetic zeolite facies, and these zeolite facies can (also claim Type B or P for cube configuration
cType) or cubic configuration (also claim P
1But be not limited to these types type).The structure of P type zeolite and characteristic are described in the works of Donald W.Breck " zeolite molecular sieve (Zeolite MolecularSieves) " (1974 and 1984 are published by Robert E.Krieger of Florida USA) to some extent.The typical divided oxide minor of P type molecular sieve:
M
2/nO·Al
2O
3·1.80～5.00 SiO
2·5H
2O
M is a n valency positively charged ion, and it is a kind of basic metal in the present invention, and promptly lithium, sodium, potassium, caesium or rubidium serve as preferred with sodium and potassium, and sodium is positively charged ion commonly used in the Industrial processes.
Therefore, sodium exists as main positively charged ion, and having a small amount of another kind of basic metal again can provide special benefit.
Now, used zeolite in the detergent composition except that numerous characteristics such as calcium binding capacity, the effective binding capacity of calcium and calcium absorption speed, also must present and can make them be used as other performance of the buider of dense detergent composition.
Be used for ability and its carrier fluid amount of the buider of this dense prescription, be also referred to as oily receptivity, directly related.Its carrier fluid amount is high more, and detergent composition can be dense more.
In addition, a kind of new non-drying process with atomizing manufacturing process that is called proposes, and powder detergent composition was produced by drying process with atomizing in the past.The carrier fluid amount of buider seems even more important in these methods.
Known now, the carrier fluid amount of some product is relevant with drying conditions, can change in a bigger scope.For example, disclosed zeolite P in EP-B-0384070, its carrier fluid amount is relevant with drying conditions, can reach 50～65% to 100～110% scope, and the numerical value that is reached under industrially drying such as spraying drying, turbine drying, flash drying or hurried～cyclic drying condition is lower.
Therefore, even the carrier fluid amount of disclosed zeolite P can make it be used as buider in the dense detergent composition among the EP-B-0384070, but under the industrially drying condition, still need further to improve its carrier fluid amount.
On the other hand, although add silicate for preventing corrosion in detergent composition, promote detergent bleach stability and play anti-redeposition effect aspect all particularly useful, its application in detergent composition obviously reduces for various reasons.
At first, most detergent composition still use zeolite A (such as can be from Crosfield Ltd., the Doucil P that company obtains) as buider.Now, as you know, when zeolite A and silicate are dry together, can form the megalump insolubles and remain on the fabric.
The second, because security reason SiO
2: Na
2The O mol ratio is among 1.6～3.2 water glass is being eliminated, and this is because it is alkalescence and has been belonged to pungency and so on.Though silicate mol ratio 〉=3.3 safety be difficult for dissolving, and the silicate of mol ratio＜1.6 is corrosive.Therefore needing a kind of new approach makes basic metal introduce unlikely the problems referred to above that occur in the detergent composition.
Have been found that a kind of particular combinations of the silico-aluminate and an alkali metal salt of P type zeolite now, it can increase the carrier fluid amount of zeolite on the one hand greatly, can make product no longer include pungency and residue do not occur on fabric on the other hand again.
Test and definition

V) sand content (grit)
Sand content is defined as the particulate percentage ratio that is retained on the 45 μ m sieves herein.With zeolite water furnishing pulpous state, ultrasonication 15 minutes is put to sifting machine (Mocker) again in beaker.Then water (hydraulic pressure 4Bar) washes sifting machine for some time.
Take off screen cloth from machine, dry in baking oven (90 ℃ 15 minutes) measure the residue amount again.
Summary of the invention
Primary and foremost purpose of the present invention provides the powdered modified silico-aluminate that has deposited alkalimetal silicate on a kind of silico-aluminate of the P of being included in zeolite granular.
